Abstract
A method for decreasing the thickness of a flexible expanded graphite sheet is provided that includes the steps of providing a a flexible expanded graphite sheet having a surface adhered to a substrate, pulling apart the sheet and the substrate with a force sufficient to separate the adhered flexible expanded graphite sheet into a removed layer and a remainder layer adhered to the substrate; and optionally repeating the foregoing steps until the remainder layer has a desired thickness.

A method for decreasing the thickness of a flexible expanded graphite sheet, comprising the steps of:
- (a) providing a flexible expanded graphite sheet having a surface adhered to a substrate;
- (b) pulling apart the sheet and the substrate with a force sufficient to separate the adhered flexible expanded graphite sheet into a removed layer and a remainder layer adhered to the substrate;
- and
- (c) optionally repeating steps (a) and (b) until the remainder layer has a desired thickness.
A method for decreasing the thickness of a flexible expanded graphite sheet, comprising the steps of:
- (a) providing a flexible expanded graphite sheet having a first thickness, a top surface, and a bottom surface adhered to a first substrate;
- (b) adhering a second substrate to the top surface;
- (c) separating the first and second substrates with a force sufficient to separate the flexible expanded graphite sheet into a first remainder layer adhered to the first substrate and a second remainder layer adhered to the second substrate;
- and
- (d) optionally repeating steps (a), (b) and (c) until a remainder layer has a desired thickness thinner than the first thickness.
A method for non-uniformly decreasing the thickness of a flexible expanded graphite sheet, comprising the steps of:
- (a) providing a flexible expanded graphite sheet having a top surface, and a bottom surface adhered to a first substrate;
- (b) non-uniformly adhering a second substrate to the top surface;
- and
- (c) separating the first and second substrates with a force sufficient to separate the flexible expanded graphite sheet into a first remainder layer adhered to the first substrate and a second remainder layer adhered to the second substrate;
- and
- (d) optionally repeating steps (a), (b) and (c) until a remainder layer has a desired non-uniform thickness.
A thin flexible expanded graphite sheet, produced by a process comprising the steps of:
- (a) providing a flexible expanded graphite sheet having a first thickness and a surface adhered to a substrate;
- (b) pulling apart the sheet and the substrate with a force sufficient to separate the adhered flexible expanded graphite sheet into a removed layer and a remainder layer adhered to the substrate;
- and
- (c) repeating steps (a) and (b), if necessary, until the remainder layer has a desired thickness that is thinner than the first thickness.
A thin flexible expanded graphite sheet, produced by a process comprising the steps of:
- (a) providing a flexible expanded graphite sheet having a first thickness, a top surface, and a bottom surface adhered to a first substrate;
- (b) adhering a second substrate to the top surface;
- (c) separating the first and second substrates with a force sufficient to separate the flexible expanded graphite sheet into a first remainder layer adhered to the first substrate and a second remainder layer adhered to the second substrate;
- and
- (d) repeating steps (a), (b) and (c), if necessary, until a remainder layer has a desired thickness thinner than the first thickness.
A thin flexible expanded graphite sheet having a non-uniform thickness, produced by a process comprising the steps of:
- (a) providing a flexible expanded graphite sheet having a top surface, and a bottom surface adhered to a first substrate;
- (b) non-uniformly adhering a second substrate to the top surface;
- (c) separating the first and second substrates with a force sufficient to separate the flexible expanded graphite sheet into a first remainder layer adhered to the first substrate and a second remainder layer adhered to the second substrate;
- and
- (d) optionally repeating steps (a), (b) and (c) until at least a portion of a remainder layer has a thickness of about 0.01 mils to less than about 0.5 mils.
